It is always amazing to me when folks are willing to hold up a piece of fictional art to contest a15,000 year old (how long have modern humans been around exactly?) historical trend. We've been developing earth-shattering technologies that could be used to royally obliterate ourselves for awhile now. Think about it, designing a metallic blade that could, literally, break every other blade wielded against it back during the various transitions from stone-age to bronze-age probably convinced many of the folks at the time that the individual wielding the metallic blade was all but invincible. And yet, somehow one metal blade wielding psychopath didn't conquer the whole world (though, some tried).
Technology breakthroughs have been occuring for thousands of years. The nuclear bomb, dynamite, machine guns, rifles, muskets, long bows, hell, even something as simple as putting a rotten corpse on a catapult and flinging it at your enemies could be considered technology. We've managed not to kill ourselves yet.
Does this new technology have the potential to destroy the human race? Maybe it will eventually, but so have a dozen other inventions throughout history. One badass, epic science fiction T.V. series is not an adequate bit of evidence to hold up and dispute this trend.
